Hi Roz,
I haven't been as active on that roll call either, but was catching up the other day and noticed all the posts about coordinating activities for solo cruisers. Because you mentioned you were traveling solo, I thought it may be of interest. I tend to not pay much attention to the names of participants, so I apologize that I didn't realize you were already a participant. I don't see the point of a meet and greet 7 days into a cruise, so I'll likely be in the laundry room instead. 🙂 Sometimes my husband does the slot pull, but he hasn't decided for this trip.
Regarding checking your onboard account, I have always done it on the app, but it may also be available on the TV. I've never checked. I try to get a hard copy on the final night to enure the copy emailed afterwards has no discrepancies.
